The woolly mammoths didn't managed to evolve to their changing environment because their food source was quickly disappearing, the climate changed rapidly, and they reproduced very slowly.
Explanation:
The woolly mammoths were huge animals that fall into the category of megafauna. They thrived during the last ice age, but they went extinct in most of their habitat soon after the end of the ice age. It is a general rule, when it comes to extinction, that the larger animals which are highly specialized are the most vulnerable to it.
In the case of the mammoths, they were huge animals perfectly adapted to the ice age climate, and were specialized when it came to their food sources. With the climate changing rapidly, the vegetation too started to change very quickly. A big problem also was the slow reproduction among the woolly mammoths, as it took too much time for the next generation to come along, and the changes in their environment were way to fast so that they can adapt in time.
With every next generation coming too late, the mammoths were too slow to follow the changes. Their food was disappearing, their numbers constantly going down, the gene pool became smaller and smaller, and they died out in most of their habitat. Only small populations managed to survive until 3,000 BC, and that was on an island north of Russia, but once the resources were gone on the island those mammoths too went extinct.

The last woolly mammoths could not evolve to changes in climate and human hunting. Fossil records and DNA analyses can trace these changes, showing how species evolve over time.
Explanation:The last generations of woolly mammoths were unable to adapt to their changing environment due to several factors. One major reason was the rapid climate change associated with the end of the last Ice Age. Their thick woolly coats and large sizes were adaptive features for the cold environment, but they became drawbacks as the earth got warmer. In addition, human hunting put extra pressure on their population.
Data from fossil records and DNA analyses can reveal how species evolve over time. Fossil evidence demonstrates physical changes in ancestral and descendant species, showing the path of evolutionary change. DNA evidence can trace the genetic mutations which arose over generations and were selected for, due to their adaptive benefits. These mutations are what ultimately drive the process of evolution.

A plate edge made of oceanic crust collides with another plate edge made of the same type of crust. What will happen ?
PLEASE HELP ASAP
Final answer:
When two plate edges made of oceanic crust collide, one plate is usually forced beneath the other in a process called subduction. The subducted plate is forced down into regions of high pressure and temperature, where it eventually melts and its material is recycled into a downward-flowing convection current.
Explanation:
When two plate edges made of oceanic crust collide, one plate is often forced beneath the other in what is called a subduction zone. The thinner oceanic plate can be thrust down into the upper mantle. This subducted plate is forced down into regions of high pressure and temperature, eventually melting several hundred kilometers below the surface. Its material is recycled into a downward-flowing convection current.
Recessive traits would never reappear if
Final answer:
Recessive traits would never reappear if all individuals were homozygous for the dominant allele, eliminating the recessive allele from the gene pool. However, this scenario is highly unlikely due to genetic diversity, sexual reproduction, and Mendelian inheritance patterns.
Explanation:
Recessive traits would never reappear if every individual in a population were homozygous for the dominant allele. This situation implies that all copies of the recessive allele have been completely removed or mutated to a dominant form within the gene pool. However, this scenario is highly unlikely in natural populations due to genetic diversity and sexual reproduction. The key to understanding this phenomenon lies in Mendelian genetics, where Gregor Mendel's experiments with pea plants demonstrated how traits are inherited from generation to generation.
Mendel's cross-breeding experiments led him to discover that dominant traits mask recessive traits in the first filial (F1) generation, making the recessive traits disappear phenotypically. However, these recessive traits reappeared in the second filial (F2) generation at a ratio of 3:1, dominant to recessive, when F1 plants were crossed. This was because the F1 generation plants were heterozygous for the trait, carrying both dominant and recessive alleles.
Therefore, for recessive traits to never reappear, it would require an unrealistically uniform genetic landscape where no individual carries the recessive allele. The principles of genetics and probability, including the application of the Hardy-Weinberg equation, illustrate how the genetic variation is maintained in populations, making the complete disappearance of recessive traits highly improbable without significant human intervention or extreme natural selection pressures.

what phenotype would you expect?
A offspring with red cones
© offspring with orange cones
® offspring with green cones
offspring with red and green cones
Answer:
The correct answer is : offspring with red and green cones.
Explanation:
Co-dominance follows non-Mendelian inheritance pattern. This is often caused due to the effect of multiple alleles of a particular gene, that get expressed simultaneously.Here, unlike in Mendelian form of inheritance pattern or incomplete dominance pattern where the effect of one allele of a gene is shadowed or blended by the other allele, both the alleles of the gene gets equally expressed in a heterozygous offspring.Therefore, the heterozygous offspring show the phenotype (both red and green cones) of both the true-breeding homozygous parents (each producing red and green cones, respectively).How many species do marine scientist estimate have not yet been discovered in the ocean?
Final answer:
Marine scientists estimate a vast majority of marine species are yet to be discovered, with only about 13% of eukaryotic species currently named out of an estimated 8.7 million. New discoveries continue, but exact numbers are hard to confirm due to small ranges and a lack of central data repository.
Explanation:
Marine scientists believe there are still many undiscovered species in the ocean. According to estimates by Mora et al. (2011), only about 13% of eukaryotic species have been named, and it is believed that there are approximately 8.7 million eukaryote species on Earth. This suggests that a vast majority of marine species remain unidentified. With new marine species being discovered regularly, it is challenging to provide an exact number, but the pursuit to understand and catalog these species is ongoing.
For example, new fish species are discovered at a rate of about 130-160 each year, suggesting a persistent flow of new findings. However, the discovery of even higher levels of taxonomic groups indicates that there could be fundamental gaps in our knowledge of marine biodiversity. Additionally, many species have very small geographic ranges, which makes them harder to find and study.
The lack of a central repository for species names and descriptions complicates the estimation of undiscovered species, but marine scientists and research programs like TOPP continue to contribute to our understanding of these complex ecosystems. These efforts are essential in light of the accelerating pace of species loss globally.

Explanation:
Gases that are less abundant in the atmosphere are called trace gases. Carbon dioxide gas is the product of respiration in animals which is then used by the plants for photosynthesis. It is present in the environment at very small concentration ( 0.04%).
Nitrogen and Oxygen both are present in the atmosphere at high proportions. Nitrogen covers 78% of the total gases volume whereas oxygen is about 28% in the atmosphere. It is vital in many biochemical processes that sustains life on Earth; for example, it is used in the production of nitrogen bases (purine and pyrimidine) and amino acid which are required for DNA and protein synthesis. Likewise, oxygen is an oxidizer which is required for aerobic cellular respiration.

Which of these is true? 1. We never get to see the far side of the moon 2. The side of the moon we see is always illuminated by the sun 3. The moon doesn't rotate 4. The moon doesn't orbit the Earth
The first statement, “We never get to see the far side of the moon” is true among all the statements given.
Explanation:
We only see one side of the moon from Earth, which is commonly referred to as the “near” side of the moon. We are able to see this side through our naked eyes due to the sunlight reflecting of the surface of the moon.
However, this is not to say that the far side of the moon does not receive sunlight at all. It does receive, but it’s just that the far side of the moon never faces the Earth and hence we never see it.
Having said that, the other statements are false. The near side itself goes through weeks of darkness, where it is not lit up by the Sun. The moon has its own axis upon which it rotates. And the moon orbits the Earth and one full rotation takes about 28 days.
Final answer:
The true statement is that we never see the far side of the moon from Earth because the Moon is in synchronous orbit. The near side is always facing Earth due to the Moon's rotational period matching its orbital period. The other statements are false.
Explanation:
Out of the options provided, the true statement is 1. We never get to see the far side of the moon. The Moon is in synchronous orbit around Earth, which means it rotates on its axis in the exact amount of time it takes to orbit Earth. This causes the near side of the Moon to always face the Earth while the far side always faces away. We can see different amounts of the near side illuminated by the sun over the course of a month, which are the phases of the Moon.
The other statements are false:
2. The side of the moon we see is not always illuminated since we observe a range of phases from new moon to full moon.3. The moon does rotate, which keeps the same side facing Earth due to its synchronous rotation.4. The moon indeed orbits the Earth approximately every 28 days.A scientist asks the question: "How fast can light travel?" Why is this a good
scientific question?

O
B. The speed of light limits the speed of human communication.
C. The speed of light is a fundamental constant in the universe.
D. The speed of light helps inform other experiments.
This question “How fast can light travel” is considered as an good scientific question because it helps inform for other experiment.
Answer: Option D
Explanation:
The speed of light is a universal physical constant and it is found to be [tex]3 \times 10^{6} \mathrm{m} / \mathrm{s}[/tex] and it is important to determine various physical units such as electromagnetic wave propagation, e.g., optics, radio waves.
This light constant is majorly used in many of the experiments and hence it is very much helpful in determining values required in an experiment. Thus the measurement of the light speed can help us inform other experiments, so we can conclude option D as correct answer.

Answer:
A malaria outbreak causing allele frequencies to change is an example of natural selection.
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.

During photosynthesis plants need constant supply of sunlight but they produce glucose a constant supply for respiration.
Explanation:
Photosynthesis take place in 2 steps, First is light dependent and followed by the light independent phase.
The light independent reaction two important molecules are formed, they are ATP and NADH. This reaction phase takes place in the thylakoid membrane of the chloroplast in the presence of sunlight. Because of this continuous supply of sunlight is required for photosynthesis. This will be followed by Calvin-cycle or light independent reaction where glucose and Carbon dioxide are the end products.
In cellular respiration glucose is the substrate along with oxygen forms energy for various metabolic activities to take place inside the organism.
So, it is seen that product of photosynthesis is the reactant for cellular respiration.
a series of coral reefs is located near a coastline in 3-5 sentences construct an argument about how people can help prevent erosion to the coastline.
Answer and Explanation:
Erosion is a natural process that occurs worldwide, and the erosion of beaches is the most common type. Although it is natural, there can be many ways to prevent it or to reduce its levels and avoid the loss of protection near coastlines.
People can help prevent erosion to the coastline by limiting (or not supporting) the construction of seawalls and sandbags that lead to beach erosion. Moreover, communities should protect NATURAL sand dunes, as they protect the coastlines from erosion. I put emphasis on natural because man-made sand dunes do the opposite. It is important to consider that beneficial (natural) sand dunes are made of layers of different types of sand, which enables the wind to gather sand in a specific spot instead of reducing it, while also allowing vegetation to grow deeper and protect the coastline.
Preventing erosion near coral reefs involves reducing pollution, reforestation, and protecting marine ecosystems.
To forestall disintegration to the shore close to coral reefs, individuals can make a few significant moves. Healthy reefs naturally protect the coast. Long-term shoreline stability is ensured by putting these measures into action.
First, keeping the reefs healthy is made easier by reducing runoff from industry and agriculture, which pollutes the water. Second, efforts to reforest can lessen the amount of sediment that accumulates in the water and harms coral. Last but not least, natural coastal protection can be provided by enforcing strict fishing regulations and protecting marine areas, both of which contribute to the delicate balance of reef ecosystems. What would be different about the graph before the evolution of photosynthetic organisms?
The oxygen component would have been smaller.
Explanation:
Photosynthetic plants / organisms evolve oxygen gas as a by-product of the process of photosynthesis. Therefore since their evolution beginning approximately 3.4 billion years ago, the atmosphere, which was once dominated by carbon dioxide, began to fill with oxygen. This period is referred to as the Great Oxygenation Event because it is also responsible for the decline of anaerobes.

proteins are found in all cell types and tissues. Contrasted to proteins found in skeletal tissue, what is the main function of proteins found in antibodies
Answer:
Protein found in antibodies provides the immunity to our body to fight against any foreign antigen.
Explanation:
Protein is the building block of our body. It forms the body tissue and even acts as a fuel source.But protein found in antibodies are slightly different in their function. In antibodies, protein develops the immunity power that shields our body from the external antigens that may cause dysfunction in our body.These antibodies drags out any antigens attacking our body systems.Antibodies are proteins that play a key role in the immune response by targeting and destroying foreign substances. They help protect the body against infections.
Explanation:Proteins have many different functions in the body. While structural proteins make up the cytoskeleton and scaffold of cells, antibodies have a different role. The main function of antibodies is to mount an immune response against foreign substances, such as bacteria or viruses. Antibodies bind to these substances and target them for destruction, helping to protect the body against infections. For example, when we get a vaccine, our bodies produce antibodies that recognize the specific pathogen introduced in the vaccine and help us develop immunity to that pathogen.
Claire is learning about the environmental factors, called mutagens, that can cause genetic mutations. Which of the following would MOST LIKELY be listed as a significant mutagen for organisms exposed regularly?
Answer:
One of the environmental factors (mutagens) that can cause mutation on an organism who is exposed to it regularly is the "ultraviolet radiation" coming from the sun.
Explanation:
"Mutagens" are agents or substances that can cause genetic mutation. The "ultraviolet radiation" coming from sunlight is one of the mutagens that can cause mutation. It damages the DNA by having an abnormal connection of the "thymine dimers." This results into the kinking of the DNA shape, thus making it difficult to copy. So, the next generation cells will have a mutated copy of the DNA. This is the reason why people are always advised to put sunscreen lotions whenever they are exposed to the sun.
The other mutagens are: x-ray radiation, chemicals, nitrites and tobacco products.
Final answer:
Radiation, specifically ionizing radiation, is a significant mutagen that organisms are regularly exposed to. It can cause DNA mutations by creating breaks in the DNA backbone and modifying bases.
Explanation:
A significant mutagen that organisms are regularly exposed to is radiation, specifically ionizing radiation like X-rays and gamma rays. Ionizing radiation can cause mutations in DNA by creating breaks in the DNA backbone and modifying bases. It can also lead to the formation of hydroxyl radicals, which can further damage the DNA.
It's important to note that not all mutations are harmful; some can be beneficial or have no effect at all. However, harmful mutations can lead to diseases such as cancer. Because of this risk, substances that cause mutations are carefully studied to determine their potential as carcinogens. Understanding and identifying mutagens is crucial for developing strategies to minimize their impact on living organisms.
Water can exist in three states of matter. Imagine examining the changes of state from solid to liquid to gas by adding___ to ice.
Answer: by adding heat to ice.
Explanation: The three states of matter are solid, liquid and gas. Ice is water in solid state. When ice is heated, it melts and changes from solid state to liquid state. When more heat is applied to water in its liquid state, it boils and changes to vapour which is gas. Water vapour exists in gaseous state.
Water can exist in three states of matter: solid, liquid, and gas. Adding heat energy to ice causes it to melt and become water.
Explanation:Water is indeed a remarkable substance, capable of transitioning between its three fundamental states of matter: solid, liquid, and gas. The transformation from a solid state, represented by ice, to a liquid state, commonly referred to as water, is known as "melting." This transition is brought about by the infusion of heat energy into the ice, which causes its molecular structure to break free from the solid lattice and transition into the more fluid, mobile state of liquid water.
Moreover, water's versatility extends to its ability to undergo another vital phase change: from liquid to gas. This phenomenon, termed "vaporization," involves the absorption of additional heat energy, which imparts sufficient kinetic energy to water molecules to enable them to escape the liquid's surface and transform into water vapor. This process of evaporation is integral to many natural phenomena, including the water cycle, where water vapor rises into the atmosphere before condensing to form clouds and, eventually, returning to Earth as precipitation.

a) Genetics refers to the study of the genome or DNA that an organism possesses. Heredity refers to the traits that are passed on from the parents to the offspring. Genetic diseases can be hereditary if they are transferred from a parent to a child. Genetic diseases can not be hereditary if they are caused by mutations in the genome and are not transferred to the offsprings.
b) A dominant trait can be described as a trait which arises due to the dominant allele. An individual can be homozygous or heterozygous for the dominant trait. A recessive trait occurs when both the alleles of a gene are recessive for a trait.

2. Compare the biomes of North Africa and Iceland. Why are they different?
Answer with Explanation:
"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.
The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.
Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."
which of the following is the best definition of peer review
Final answer:
Peer review is an evaluative process conducted by experts in the field who examine research before its publication to ensure quality, reliability, and validity in the scientific community.
Explanation:
The best definition of peer review is a process where researchers submit their work to be scrutinized and critiqued by other experts in the same field before it is published in a scientific journal or presented to a broader audience. The purpose of this process is to maintain high standards of quality, improve performance, and provide credibility. Peer reviewers evaluate the research on multiple criteria, including the rationale, methodology, ethical considerations, statistical analyses, and the conclusions of the research. They also assess the significance of the results to advance the discipline's knowledge. Authors receive constructive feedback and might have to revise their work, which contributes to the reliability and validity of scientific knowledge.
Peer review is conducted anonymously, which is critical for maintaining objectivity in the process. By not knowing each other's identities, reviewers and authors are likely to be more honest and unbiased in their critique and response, leading to a more thorough and rigorous review. This anonymous process also helps to prevent conflicts of interest and promotes a fair evaluation based on the quality of the work itself.
when is acetyl CoA produced?
Acetyl CoA is produced at many steps in our body, but mainly its produced by decarboxylation of pyruvate.
Explanation:Acetyl CoA is the gateway molecule to Kreb's Cycle. This molecule can pass from the cytoplasm to mitochondria which can be used in further metabolic processes.
In case of aerobic respiration, glucose undergoes a metabolic breakdown to produce two molecules of pyruvate and a few NADH and ATP. But this pyruvate cannot enter the mitochondria where the next step i.e Kreb's Cycle is going to take place. This is then taken up by Pyruvate Decarboxylase complex or PDC where pyruvate is acted upon by enzyme Pyruvate Decarboxylase which also uses an oxidized NAD and Coenzyme A to produce a molecule of carbon dioxide, NADH and Acetyl CoA.
